Very interesting historical information Günther, thank you!

    Don’t forget about the Ausbausystem 3 demo block prototype set which you discovered in the Lectron, GmbH warehouse.

    For my new home, I am going to make a wall display unit of the FM Stereo block and circuit that you helped develop for the 50th anniversary jubilee. It will feature the speaker substitutions that Frank pioneered to have enhanced sound quality.
